An Enhanced Algorithm In Tracking Characteristic Modes Of Dielectric Objects

Tracking PMCHWT-based characteristic modes (CMs) of dielectric or magnetic objects still remains a challenging task due to the presence of non-physical modes, but developing a robust tracking algorithm is essential to observe modal behavior over frequency. Thus, our efforts continue in enhancing an existing tracking algorithm which is based on eigencurrent correlation and far-zone eigenfield orthogonality for more reliability and efficient computational time. Also in this paper, some important findings about tracking are discussed.
